Smithmal, you should probably plan to just order one for fall anyway. I've got a small Nordland (just rooted, obtained from a generous member who gave me a cutting). And I don't mind sharing cuttings once it's big enough to have any. (It may be big enough by this fall, but more likely it'll be another year before it's big enough). You'd probably find other members on here who feel the same way. But here's the thing: First, anyone willing to make those cuttings probably can't make them until the fall anyway. Second, I don't think you should plan to put a first year cutting tree in-ground in Maryland anyway. I mean, you could if you really want to do extreme protection for it. But if you seriously want a Nordland in ground in Maryland, you'd be best off keeping it potted until it has some maturity to it. It's easier to protect it while it's young (you can move the pot). Young trees (younger than 3 or 4 years) are more susceptible to winter kill than more mature trees. So if you're in it for the long haul for in ground trees anyway, what's the harm in letting them get some size and maturity before you put them in ground? That'd be my advice anyway. Not saying you can't put them in-ground younger, but I think your odds of success go up if you don't rush it.
